IC is the abbreviation of Integrated Circuit (integrated circuit), refers to the integration of multiple electronic components (such as transistors, capacitors, resistors, etc.) on a chip. The IC in the mobile phone mainly refers to the chip, which is the core controller of the mobile phone, responsible for managing important functions such as battery, communication, computing, storage and display.
In the baseband chip, there are multiple modules such as processor, modem, sound card, streaming media decoder, RF front end, etc. The coordination and operation of these modules make the communication and entertainment functions of the mobile phone realized. At the same time, with the continuous upgrading of functions, the IC in the mobile phone is becoming more and more complex, and the performance is becoming more and more powerful. More and more mobile phone manufacturers began to launch their own mobile phone chips, such as Huawei's Kirin chip, Xiaomi's Snapdragon chip, etc., their emergence has greatly promoted the development of the mobile phone industry.
